how to troubleshoot a Ford F-150 13th Generation (2015-2020) with no sound from the speakers

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to avoid any electrical shorts.
• Tools required: socket set, multimeter, panel removal tool.

2. Inspect and Repair Wiring

• Step 1: Remove the head unit.

  • Use a panel removal tool to carefully detach the trim around the head unit.
  • Unscrew and pull out the head unit from the dashboard.

• Step 2: Check wiring connections.

  • Inspect the wiring harness for any loose connections, frayed wires, or corrosion.
  • Reconnect any loose wires or replace damaged sections of wiring if necessary.

3. Test and Replace Speakers (if needed)

• Step 1: Remove a speaker from the door panel.

  • Use a socket set to remove screws securing the speaker.
  • Carefully detach the speaker from the wiring harness.

• Step 2: Test the speaker.

  • Use a multimeter to measure the impedance of the speaker (should typically be around 4-8 ohms).
  • If the speaker shows no continuity or does not match the expected impedance, replace it.

4. Reassemble Components

• Reinstall the head unit and secure it with screws.
• Reattach the trim panel carefully.
• Reconnect the battery and test the audio system.
